Freshwater Biomes
Description: The freshwater biome consists of rivers, lakes, ponds, creeks, and
streams. Freshwater is defined as having a low salt content (typically less than 1%).
Due to the purity of the water and lack of harsh salts freshwater biomes are home to a
broad variety of plants and animals. Freshwater biomes can be found almost anywhere
and vary greatly in size. Since freshwater biomes are so spread out it may seem as if
this is the largest of all biomes but this is not true. However, freshwater biomes are still
very important as they provide us with many essential resources.
Resources:



Hydroelectric power
Food
Water for drinking, cooking, etc.
Problems:




Dam building- fish are barricaded when they travel to reproduce. No reproduction
leads to the extinction of fish species.
Over fishing- if a certain species is overfished it can also lead to extinction of fish
species.
Pollution- the water becomes polluted from the dumping of garbage, factory
fumes, and run-off from both farms and factories.
Global warming- the increase in temperatures is causing the water to be
evaporated faster and the plants in or around the biome are dying and animals
are losing their food source.
